SYSTEM FOR WIRELESSLY TRANSFERRING ELECTRICAL POWER

An embodiment of the present invention provides a system () for wirelessly transferring electrical power to an electrical load () comprising: a feeding device () and a device to be fed () physically separate and independent from the feeding device; wherein the device to be fed () comprises: the electrical load to be fed, a control circuit () adapted for generating a clock signal, and a receiving apparatus () of the electrical power connected to the electrical load (); and wherein the feeding device () comprises at least one transmission group () of the electrical power that includes: a transmitting apparatus () adapted for making a non-conductive electrical coupling with the receiving apparatus () of the device to be fed (), a signal management circuit () adapted for receiving the clock signal generated by the control circuit () of the device to be fed () and for generating a pilot signal having a frequency proportional to the frequency of the clock signal, and a power circuit () adapted for receiving the pilot signal generated by the signal management circuit () and for applying to the transmitting apparatus () a voltage wave that is periodically variable over time with a frequency equal to the frequency of the pilot signal.
